Can skin tags spread? The short answer is no, skin tags do not spread from person to person or from one part of your body to another through contact. They are benign growths, and while their exact cause isn’t fully understood, they are not contagious.
It’s completely understandable to be concerned when you notice a new skin tag appearing, or if you’re unsure about their behavior. Many of us have encountered these small, often harmless growths, and questions about whether they can spread are very common. Perhaps you’ve seen one on your neck and then noticed another on your arm and wondered if the first one “caused” the second. Or maybe a friend mentioned having them, and you’re curious if they could be passed on. Rest assured, you’re not alone in asking these questions. As a dermatologist, I see this confusion often. The good news is that skin tags are not contagious, and you can’t spread them to someone else, nor can they “spread” across your own body like a cold. In this article, we’ll explore exactly what skin tags are, why they appear, and importantly, confirm that they don’t spread. We’ll also discuss safe and effective ways to manage them if they bother you.

Understanding Skin Tags: What Are They, Really?
Skin tags, also known medically as acrochorda, are small, soft, benign (non-cancerous) growths that hang off the skin. They are typically flesh-colored or slightly darker and can range in size from tiny, barely visible specks to larger, pedunculated (stalk-like) growths. You’ll most commonly find them in areas where skin rubs against skin or clothing, such as the neck, armpits, groin, eyelids, and under the breasts.
While the exact cause of skin tags remains a mystery, dermatologists believe they are related to factors like:
- Friction: Constant rubbing of skin against skin or clothing can irritate and stimulate growth. This is why they are common in areas like the neck and armpits.
- Genetics: There might be a genetic predisposition, meaning they can run in families.
- Hormonal Changes: Fluctuations in hormones, such as during pregnancy or due to conditions like diabetes, can sometimes be associated with their development.
- Weight: People who are overweight or obese tend to have more skin tags, likely due to increased skin folds and friction.
- Insulin Resistance: Some studies suggest a link between skin tags and insulin resistance or metabolic syndrome.
It’s important to remember that skin tags are not caused by any virus or bacteria, which is why they cannot be transmitted to others or spread on your own body through infection.
Can Skin Tags Spread? Debunking the Myth
This is the question on everyone’s mind, and the answer is a resounding no. Skin tags are not contagious, and they do not spread.
Let’s break down why this myth might exist:
- Appearance of Multiple Tags: Many people develop multiple skin tags over time, often in the same areas prone to friction. This can create the impression that they are spreading, but in reality, it’s more likely that the underlying factors causing them are still present, leading to new growths in similar locations.
- Misidentification: Sometimes, other skin conditions might be mistaken for skin tags. Certain viral infections, like warts, can spread and might look superficially similar to skin tags, leading to confusion.
- Scratching or Irritation: While scratching a skin tag won’t cause it to spread to a new area, persistent scratching can cause irritation, bleeding, or even lead to the tag falling off prematurely. This can sometimes be mistaken for it “spreading” or moving.
Think of it like this: If you have a predisposition to getting moles, you might develop several moles over your lifetime. This doesn’t mean your first mole “spread” to create the others. Similarly, if your skin is prone to developing skin tags due to friction or other factors, you might develop more over time, but they are independent growths.
Why Do I Have So Many Skin Tags?
As we touched upon, several factors can contribute to the development of multiple skin tags. Understanding these can help you manage them and potentially reduce the likelihood of new ones forming:
- Friction is a Key Player: Areas where skin folds or rubs together are prime real estate for skin tags. This includes the neck, armpits (axillae), under the breasts, and the groin area. Wearing tight clothing or jewelry that constantly rubs against the skin can also contribute.
- Weight Matters: Increased body weight often leads to more skin folds and increased surface area where friction can occur, making individuals with obesity more prone to skin tags.
- Hormonal Influences: Pregnancy is a time of significant hormonal shifts, and many women notice an increase in skin tags during this period. These may even disappear after delivery. Similarly, conditions affecting hormone balance can play a role.
- Metabolic Health: Emerging research suggests a connection between skin tags and conditions like insulin resistance, type 2 diabetes, and metabolic syndrome. If you have numerous skin tags, it might be a subtle indicator to discuss your overall health with your doctor. For more information on metabolic health, the National Institute of Diabetes and Digestive and Kidney Diseases offers valuable resources.
When to See a Dermatologist About Skin Tags
While skin tags are harmless, there are times when it’s a good idea to consult a dermatologist:
- Uncertainty: If you’re not sure if a growth is a skin tag or something else, it’s always best to get it checked. Some skin conditions can mimic skin tags but require different treatment.
- Irritation or Discomfort: If a skin tag is constantly getting caught on clothing or jewelry, or if it becomes irritated, red, or bleeds, a dermatologist can safely remove it.
- Cosmetic Concerns: If skin tags are in a visible area and you find them bothersome for cosmetic reasons, removal is an option.
- Sudden Appearance or Change: If you notice a rapid increase in the number of skin tags, or if an existing one changes in color, size, or shape, it’s crucial to have it evaluated by a doctor to rule out other possibilities.
Safe and Effective Ways to Manage Skin Tags
Since skin tags don’t spread, you don’t need to worry about them multiplying due to your actions. However, if they are causing discomfort or you simply don’t like the way they look, there are several safe and effective removal options available. It’s important to note that attempting to remove skin tags at home using unverified methods can be risky and lead to infection, scarring, or excessive bleeding. Always consult with a healthcare professional for removal.
Professional Removal Methods
These are the safest and most common methods performed by dermatologists:
| Method | Description | Best For | Pros | Cons |
|---|---|---|---|---|
| Cryotherapy (Freezing) | Liquid nitrogen is applied to the skin tag, freezing it. The tag will typically fall off within a week or two. | Small to medium-sized skin tags. | Quick, relatively painless, minimal risk of scarring. | May require more than one session for larger tags; temporary blistering or discoloration can occur. |
| Surgical Excision (Cutting) | The skin tag is cut off using a sterile scalpel or surgical scissors. Often used for larger tags or those with a wider base. | Larger skin tags, those with a narrow stalk. | Immediate removal; effective for larger growths. | May require local anesthetic; can cause minor bleeding and a small risk of scarring. |
| Electrocautery (Burning) | A heated needle or probe is used to burn off the skin tag. This method also helps seal the wound, reducing bleeding. | Various sizes, especially those with a stalk. | Effective, seals the wound to prevent bleeding, minimal scarring. | May cause a temporary burning sensation; local anesthetic might be used. |
| Ligation | A surgical thread or fine wire is tied around the base of the skin tag to cut off its blood supply. The tag will eventually wither and fall off. | Skin tags with a distinct stalk. | Non-invasive (no cutting or freezing), can be done at home with caution (but professional is recommended). | Takes time for the tag to fall off; can cause temporary discomfort if the ligature is too tight. |
Home Care & Prevention Tips
While you can’t prevent all skin tags, you can minimize the conditions that encourage their growth:
- Manage Friction: Wear loose-fitting clothing in areas prone to skin tags. If you experience chafing, consider using a barrier cream or talc-free powder to keep the skin dry and reduce friction.
- Maintain a Healthy Weight: Losing excess weight can reduce skin folds and the associated friction.
- Good Hygiene: Keeping skin clean and dry, especially in folds, can help prevent irritation.
- Avoid Irritation: Be mindful of jewelry or clothing that constantly rubs against your skin.
It’s crucial to reiterate that while some over-the-counter products claim to remove skin tags, their effectiveness can vary, and they may carry risks. Always prioritize safety and consult a dermatologist for the best advice.
Frequently Asked Questions About Skin Tags
Q1: Can I catch skin tags from someone else?
A: No, skin tags are not contagious. You cannot catch them from another person through skin-to-skin contact or sharing items.
Q2: If I have one skin tag, will more appear on my body?
A: While one skin tag doesn’t cause others to “spread,” you might develop more over time if the underlying factors (like friction, genetics, or hormonal changes) are still present. It’s not a contagious spread, but rather a tendency for your skin to develop these growths under certain conditions.
Q3: Is it safe to cut off a skin tag myself?
A: It is generally not recommended to cut off skin tags yourself. This can lead to infection, significant bleeding, pain, and scarring. Professional removal by a dermatologist is the safest option.
Q4: Can skin tags appear on my face?
A: Yes, skin tags can appear on the face, particularly on the eyelids or around the neck area, where skin is thinner and can be subject to friction from clothing or accessories.
Q5: Do skin tags hurt?
A: Most skin tags are painless. However, they can become irritated or painful if they are rubbed by clothing, jewelry, or if they get snagged.
Q6: Are skin tags a sign of cancer?
A: No, skin tags are benign growths and are not cancerous. They do not turn into cancer. However, if you notice any skin growth that changes rapidly or looks unusual, it’s always best to have it checked by a doctor.
The Takeaway: Reassurance and Action
Understanding skin tags can bring significant peace of mind. The most important truth to remember is that skin tags do not spread. They are not infectious, and you cannot transmit them to others or cause them to multiply on your own body through contact. While they might appear in clusters or new ones may develop over time due to factors like friction and hormonal changes, this is a characteristic of the growths themselves, not a sign of them spreading like an illness.
If you have skin tags that cause you discomfort, irritation, or cosmetic concern, you have safe and effective options for removal through your dermatologist. They can accurately diagnose any skin growth and recommend the best course of action, whether it’s monitoring, lifestyle adjustments, or professional removal. By addressing friction and maintaining overall health, you can also help minimize the likelihood of new skin tags forming. Remember, your skin health is a journey, and seeking expert advice is always a confident step forward.
